JUPITER, Fla. — Edwin Diaz insisted he had no hard feelings regarding the Mets renewing his contract at $607,425 instead of being able to reach an agreement with his new team — as the Mets did with their 25 other pre-arbitration players.

“I think this is a business,’’ Diaz said at First Data Field in Port St. Lucie. “They have their decision and I have my decision. Everybody’s happy. We’re at a good point right now.”

Diaz, who struck out two in a scoreless inning in the Mets 3-1 loss to the Marlins at Roger Dean Stadium later on Tuesday, came to the Mets along with Robinson Cano from Seattle in exchange for Jay Bruce and prospects.

The 24-year-old led the majors with 57 saves a year ago and has been penciled in as the team’s closer, but he won’t be paid like it. Diaz, though, said he would keep his focus on the field.

“I can’t say I feel bad with the team,’’ Diaz said. “I can control what I do on the field. They made that decision. That’s fine. … I just put up numbers and play for my team. … My agency tried to protect me and I think they made the right decision.’’

After the decision was made Monday, GM Brodie Van Wagenen said there was “no animosity” toward Diaz.

In recent years, the Mets had renewed just two other players — Jacob deGrom and Noah Syndergaard, who are represented by CAA, which until he was hired by the Mets is where Van Wagenen was an agent.

Travis d’Arnaud has played two games at DH and is scheduled to catch in a B game in Port St. Lucie on Thursday.

“We’re anxious to see him behind the plate for a couple innings,’’ Mickey Callaway said of d’Arnaud, who underwent Tommy John surgery last April. “We’ll move on from there.’’

Because d’Arnaud hasn’t played defense yet, Callaway said the team hasn’t determined how many catchers it will carry to start the season. It’s conceivable they could have three, with Wilson Ramos as the starter and Devin Mesoraco and d’Arnaud as backups.

Callaway said Amed Rosario, who was hit by a pitch in his left hand Monday, was “a little tender” in the area Tuesday and the team would “evaluate day-to-day’’ to determine when the shortstop would return.

The Mets made five more errors (two by Luis Guillorme, as well as miscues by Mesoraco, Braxton Lee and Cody Bohanek). Despite the fact most of the errors came from players that likely won’t be in Queens much this season, Callaway wasn’t pleased.

“I don’t care who you are, if you come up here and are playing in a game, we expect the best out there,’’ Callaway said. “We’ll address it.’’

Jason Vargas allowed four hits but no runs in 2¹/₃ innings. He said he didn’t feel “as crisp” as he’d like.

Luis Avilan struck out four batters in 1 ²/₃ scoreless innings to continue his impressive spring. “He has a lot of deception,’’ Callaway said of the 29-year-old. “The kid throws the ball over the plate. He has a great idea of how to pitch.”

Brandon Nimmo, in his second game back from being out with a virus, went hitless again and is 0-for-7 with four strikeouts.

Keon Broxton made a nice catch in center off a Rosell Herrera fly ball in the second and turned it into a double play when he caught Jorge Alfaro off second base.

Wednesday’s schedule: The Mets are off. They return to action Thursday at 1:05 p.m. in West Palm Beach, when they will get their first look at Washington since Bryce Harper officially became a former National by signing with the Phillies. Jacob deGrom is slated to make the start.
